Indoor Radon Monitoring in Northern Iran Using Passive and Active Measurements

Relationships between radon concentration, building materials and room ventilation are studied. The relationship can be used to estimate annual average radon concentration from results of measurements made during one season only. A total of 1124 samplers in Lahijan, Ardabil, Sar-Ein and Namin are in...

Description
Summary:Relationships between radon concentration, building materials and room ventilation are studied. The relationship can be used to estimate annual average radon concentration from results of measurements made during one season only. A total of 1124 samplers in Lahijan, Ardabil, Sar-Ein and Namin are installed. For quality assurance, 281 active measurements and double sampling are carried out. Basements are more popular in Ardabil with cooler winter climate and have the highest radon activity concentration compared with other floors. It is suggested that the mild climate in Lahijan allows more natural ventilation in all seasons, while the cold autumn and winter in Ardabil permits least likelihood of natural ventilation.
